Flushing and filling the solar system
WARNING!
Risk of scalding!
If the medium enters strongly heated, empty collectors, pressure
surges caused by vaporisation can occur.
Î In order to prevent the medium from boiling in the
collectors, do not fill or flush the system during times
of strong solar irradiation.
ATTENTION!
Damage to the device caused by underpressure!
If the lid is tightly closed, the tank will be depressurised during
the filling process.
Î Open the tank for the filling process!
